I have an old chuck and duck 16" chipper. I was told its an altec maybe from 60s-70s. I need a few things like how to make my blade adjustment screws stay in place and need bearings for it how hard are they to and the cutter bar how to flip and set it up. Im not sure of the model or year because guy i bought it off put a bigger drum on it and changed alot of stuff. Any help will be a plus i have not yet tore into the bearings im not sure if theyre bad yet or not just want to replace them before they are destroyed
